System and method for conducting and securing transactions when blockchain connection is unreliable

ABSTRACT

A system for transacting in an environment with intermittent connectivity via a network backbone to a blockchain. A merchant device transmits a set of credentials for an ad hoc network to a buyer device and establishes a private peer-to-peer ad hoc network connection with the buyer device. It then conducts a transaction with the buyer device via the private peer-to-peer ad hoc network. If no network connection is available to a transaction blockchain, the merchant device stores a record of the transaction until such network becomes available and later sends the record of the transaction to the transaction blockchain.

BACKGROUND Field of the Art

The disclosure relates to the field of computing devices, and more particularly to the field of handling electronic transactions using digital currency.

Discussion of the State of the Art

Some of the cybercurrency systems in use today have serious shortcomings, because they use blockchain. As the blockchain gets longer, transactions can take as long as half an hour, or more, to reach a critical number of confirmations in the blockchain. This latency in concluding a transaction leads to some uncertainty about the value of the transaction until it closes. Combined with the current volatility of some cybercurrency, especially small transactions are affected, so that micro transactions become unattractive. For example, in a transaction that is equivalent to 50 cents and takes half an hour to conclude, the currency may fluctuate as much as 25 percent or even 50 percent in that half hour. Thus, a user may lose a large amount of the value of the transaction in the time required to complete the transaction.

One of the problems in digital currency systems is how to control those systems in a country or regional currency, and, more in particular, how to Bootstrap a system in such a way that it can be “taken over” in a friendly way by the government of that country or region, without any disruption or problems at all.

Known to the inventors is a system for executing cybercurrency transactions, especially small transactions, to avoid currency fluctuation risks and to close transactions quickly. By using a set of high-performance scalability tests, users can quickly get a repeatable test infrastructure to validate the performance and scaling goals for such a system. Further, they can build a system that they can use to understand and design the final product and can show to potential partners and investors. This goal, of product design and demonstration, can be achieved by building the system in phases, using the same generated dataset as input for each phase, and measuring performance of each phase in a repeatable way.

What is clearly needed is a system and method for organizing and managing a regional or country-wide blockchain transaction system with multiple partners, so that it can be started initially as a completely private system, but then be converted easily and without any disruptions into an official currency system.

While cryptocurrencies certainly have advantages, such as anonymity, portability etc., some of these are not as real or strong as they are usually thought to be. For example, anonymity is considered a very important and fundamental element of cryptocurrencies, but is not completely present; for instance, an interested party can track transactions based on the public nature of the blockchain easily. Similarly, portability has recently become a problem, as criminal blackmail schemes lead people into handing over Bitcoins or Ethereum tokens, and then disappear into the night with a universal serial bus (USB) stick full of loot, often after home invasions or similar occurrences.

What is clearly needed is a system and method for storing, transacting and securing cryptocurrencies at much higher speeds and making them know-your-customer (KYC) and anti-money laundering (AML) standards compliant, providing additional advantages without further creating problems. That will by and large prevent such problems, as the transaction now becomes easily and speedily traceable.

In some cases, a system for transacting using a blockchain and/or a cryptocurrency may need to remain operable in an environment without good network backbone connectivity to the blockchain. What is clearly needed is a system for conducting transactions using a blockchain when blockchain connectivity to a network backbone is intermittent or unreliable.

There are elements with first and second generation cryptocurrency solutions that limit their growth for mainstream use, where individuals can use them in everyday activities like they use a credit card or cash today; it is an object of the present to alleviate this problem by providing for robust transaction capabilities in real-world, intermittently-connected networking situations.

SUMMARY

Accordingly, the inventor has conceived and reduced to practice, a system and method for conducting and securing transactions when blockchain connection is unreliable.

In some cases a system for transacting in an environment without connectivity between a network backbone and a blockchain, a merchant device such as a phone or point of sale offers or transmits a set of credentials for an ad hoc network to close the transaction (by offering or transmitting an embedded set of optional ways to connect an ad hoc network between a buyer phone and a merchant phone or point of sale), and allows a direct exchange of multiple handshakes to secure the transaction, Both phones (or the consumer phone and the merchant phone and/or point of sale) will then keep a record of this transaction and try at the next opportunity to send this transaction over the network backbone to a blockchain. In yet other cases, each time such a client or merchant devices encounters other known, trusted devices on a P2P network, they may send an encrypted copy of their mutual transactions to the trusted devices, thereby enabling the encrypted copy to be transmitted over the network backbone to a blockchain as quickly as possible via repeated attempts by one or more trusted devices that may have better connectivity than the original sending device. A device that may or may not have been involved in the actual transaction may transmit the transaction to the network backbone and propagate it to the blockchain. Furthermore, in some cases, such client and/or merchant devices may be antitamper-hardened devices.

DETAILED DESCRIPTION

The inventor has conceived, and reduced to practice, a system and method for conducting and securing transactions when blockchain connection is unreliable.

Definitions

The term “cryptocurrency” as used herein includes not only its classic meaning but can also mean a representation of value in digitized form, secured by encryption, which may be transferred to others or exchanged with others for goods and services. Cryptocurrencies are typically not associated with a governmental authority, although it would be possible for a governmental authority to issue one. The definition of a cryptocurrency does not necessarily require distributed, unmanaged tracking and processing, although all major cryptocurrencies currently in use are so defined. Cryptocurrencies are often referred to a digital currencies or virtual currencies, and the valuation associated with cryptocurrencies is often referred to as coins or tokens, with fractional parts of a coin or token typically being allowed to be transferred or utilized.

The phrase “real currency” (aka fiat money) as used herein means the official currency of a country, region, or other globally-recognized governmental entity. For example, the U.S. dollar is the official currency of the country of the United States of America, the Euro is the official currency of the region of the European Union, and the Scottish bank notes are an officially recognized currency in Scotland, notwithstanding the fact that they are tied to the value of the British Pound.

The phrase “functional area” as used herein means any industry, grouping, association, political region (for example special economic zone), type of work, or other field of human endeavor, which may or may not correspond to a geographical area.

The phrase “geographical area” as used herein is used in its common meaning as any demarcated area of the Earth. Geographical areas are often, but not always, defined by agreed-upon borders such as between countries, states, counties, and cities.

The terms “mine” or “mining” as used herein mean incentivizing nodes to provide computer processing power to validate transactions by generating a small additional portion of the valuation associated with a blockchain database for each successful entry validation in that database, and giving that small portion to a node or nodes that perform(s) the successful entry validation.

The term “node” as used herein means any one of a plurality of computers that validate transactions in the blockchain database as part of a peer-to-peer network.

“Artificial intelligence” or “AI” as used herein means a computer system or component that has been programmed in such a way that it mimics some aspect or aspects of cognitive functions that humans associate with human intelligence, such as learning, problem solving, and decision-making. Examples of current AI technologies include understanding human speech, competing successfully in strategic games such as chess and Go, autonomous operation of vehicles, complex simulations, and interpretation of complex data such as images and video.

“Machine learning” as used herein is an aspect of artificial intelligence in which the computer system or component can modify its behavior or understanding without being explicitly programmed to do so. Machine learning algorithms develop models of behavior or understanding based on information fed to them as training sets, and can modify those models based on new incoming information. An example of a machine learning algorithm is AlphaGo, the first computer program to defeat a human world champion in the game of Go. AlphaGo was not explicitly programmed to play Go. It was fed millions of games of Go, and developed its own model of the game and strategies of play.

Unmanaged, distributed network, transactional databases (commonly known as “blockchain” databases) can be used to facilitate transactions in a manner that was previously not possible: they allow transactions between users without any form of centralized authority that has control over those transactions. The keys to this new technology are encryption, which allows security of the transaction, and distributed public confirmation, which allows trust in the validity of the transaction. There are innumerable uses for this new technology, such as transferring money, creating automatically-executing contracts, forming and automatically executing escrow transactions, etc. In fact, any asset that can be represented in digital form can be transferred or exchanged using blockchain databases.

The first, and still most common, use of blockchain databases was to enable the use of cryptocurrencies without a centralized controlling authority. However, while blockchain databases have significant advantages for use in cybercurrencies, they also have serious drawbacks, which continue to plague the cybercurrencies that use blockchain. As the blockchain for a given cybercurrency gets longer, transactions can take half an hour, or more, to reach a critical number of confirmations for validation of the transaction in the peer-to-peer network that manages the blockchain. This latency in concluding a transaction leads to substantial uncertainty about the value of the transaction until it is finalized. Combined with the current volatility of some cybercurrencies, this can lead to large fluctuations in value between the time that a transaction is initiated and the time that it is finalized. This valuation uncertainty is a problem for all sizes of transactions, but makes very small transactions particularly unattractive. For example, using existing blockchain-based cybercurrencies, buying a cup of coffee would be problematic. Not only would the buyer and seller need to wait on the order of half and hour for the transaction to complete, the cybercurrency equivalent of two dollars sent by the buyer could end up being the equivalent of three dollars by the time that the transaction is confirmed and finalized. Thus, each party to a transaction may gain or lose a large amount of the value of the transaction in the time required to complete the transaction.

Cybercurrencies, as they currently exist, are monolithic, which is to say that they are global, single-tier, single-unit currencies. They are global in the sense that there are no regional restrictions on transactions. Anyone with a computer anywhere in the world can make a transaction with anyone else anywhere in the world. They are single-tier in the sense that there are no higher or lower tiers of cybercurrency within the same system for which they can be traded or exchanged. They are single-unit in that there is a denominated unit (often referred to as a “coin” or “token”) which is the unit of value for all transactions. Fractions of a denominated unit may be transferred, but the denominated unit never changes.

The problem with monolithic cybercurrencies is that the time for processing of transactions grows as the blockchain upon which they are built grows. In certain cybercurrencies currently in use, the processing time for transactions can half an hour, or more. This is the time required to reach a critical number of confirmations for validation of the transaction in the peer-to-peer network that manages the blockchain. The longer the cybercurrency is in operation, the larger the blockchain grows, and the longer the latency becomes between the initiation of a transaction and its finalization.

This latency makes certain transactions untenable for time reasons. This is particularly the case for small transactions where the buyer and seller would not ordinarily stand around waiting for the transaction to complete. For example, in buying a cup of coffee, the buyer and seller expect to conclude the transaction within a few seconds, or within a minute or two at the most. The buyer orders the coffee, makes the payment, and the seller hands the buyer the coffee, all within a minute or two. Having to wait half an hour or more for the transaction to complete makes this sort of small value transaction untenable.

This latency also makes certain transactions untenable for valuation reasons. A long latency creates uncertainty in concluding a transaction leads to substantial uncertainty about the value of the transaction until it is finalized. The longer the latency and the higher the volatility of the cybercurrency, the more uncertainty is created in value, and the less tenable a cybercurrency is for making that transaction. This problem exists for transactions of all values, but for larger transactions, the parties involved may be willing to take the risk of fluctuation for any number of reasons (e.g., the value to them of making an anonymous transaction may be higher than making the transaction using other types of currency). For smaller transactions, the reasons for taking the risk of value fluctuation are largely eliminated. For example, in the example of the purchase of a cup of coffee, there is little reason for either of the parties involved to care whether the transaction is anonymous. Since cybercurrencies can be extremely volatile, a half hour latency can cause the parties to a transaction to gain or lose a large amount of the value of the transaction in the time required to complete the transaction.

In one embodiment, the multi-tiered blockchain database system can be used to improve the viability of small value cybercurrency transactions. The improvement involves creating multiple tiers within the cybercurrency with characteristics that reduce the latency between the initiation and finalization of transactions, such that waiting times and risk of value fluctuation for both the buyer and seller are reduced to acceptable levels for small value transactions.

In certain embodiments, a cybercurrency system may be enhanced to reduce these latencies by including one or more tiers in which transactions are limited to those of a lesser denomination, with a limited number of ledger transacting nodes and a limited number of gateways interacting between the general area of unlimited currency and the demarcated area. In some embodiments, the tiers may represent different tiers of currency may be issued, and exchanges of cybercurrency among the tiers may be allowed. In some embodiments, the tiers may be limited to a certain geographical region, where the cybercurrency in that section may be traded at a fixed rate to another currency in the same area, which may be a real currency rather on a major cryptocurrency. In some such embodiments, a central issuer, or bank, with a reserve, may be allowed stabilize the cybercurrency or to tie the value of the cybercurrency to the local real currency. In some embodiments, so called “mixer wallets” containing more than one cryptocurrency may be blocked or confiscated to avoid misuse of funds for illegitimate purposes.

In one embodiment, lower tiers of cryptocurrency would be restricted in in a number of ways. Lower tiers of cryptocurrency would be allowed to handle only fractional currency, that is, currency that is a fraction of a whole currency unit, usually equivalent to coins. The machines that process transactions in lower tiers of cryptocurrency could process only in their own region, and only fractional transactions. Also, because only fractional transactions of fractional currency occur in these lower tier currencies, no currency mining could occur, because no mining is allowed in these lower tier currencies. If a user wants to change the between tiers, the currency would be reserved via gateways and blocked into the ledger in the main region and transferred into the lower region and made available as fractional currency. A small portion of any transfer would be allocated to the operators of the ledger machines in each region to pay operating costs. With no mining occurring in the regions, and with the regions being regionally limited in range, the cost of operation would be much lower. Also, the local fractional currency could be, for example, bound to a local physical currency such as, for example, the U.S. dollar or the Euro, rather than to a cybercurrency such as Bitcoin or Ether, so there might be a local master currency available, issued by the conversion gateway, which would be paid for by currency in the upper domain and then actually converted by the gateways into a local physical currency. Those gateways might act as central banks, rather than as gateways, issuing a fractional currency only. Thus the transactions may be made faster and less vulnerable to currency fluctuations.

In some embodiments, the ledgers may be split by years, with the current ledgers containing only transaction for the current year or two, and all previous transactions kept in archived ledgers, accessed only if a user has a wallet with an old balance. In such a case, as soon as the user wants to use the old balance, the wallet is retrieved from the archive, updated, and removed from the archive. Thus archived wallets may take a little longer to transact, but current wallets are much faster, because the ledger is kept current only in the ledger currency. Because the ledgers are regionalized, they can be much smaller and thus process transactions much more quickly.

It is important to note that the regionalization of lower tier currencies does not mean a ledger is limited to one country. For example, in North America, each region could contain a piece of Canada, the United States, and Mexico. Thus, including multiple jurisdictions could avoid putting a region under the control of just one country. Wallets could simultaneously contain the physical currency of multiple regions, such as, for example, Euros, dollars, and yen. Most people spend currency in their home region, so merchants could execute transactions much more cheaply, because of the reduced risk of currency fluctuations in most cases.

Further, in some embodiments, when liquidity runs below a certain level, due to large outflow, a program or an AI module in the system can take at least one of several countermeasures: a) it can change exchange rate to reduce outflow, b) it can offer an interest for delaying a conversion, or c) it makes a cash call on certain members of a reserve group to allow a larger reserve to be built up quickly and thus maintain liquidity. This process can be triggered in an automated way by software and or an AI supervisory module (not shown) running as part of the management software of the system on at least one of the servers or as part of the EVM system (or similar) or both.

In some embodiments, enhancements to existing blockchain technology may be used to reduce the latency associated with current cryptocurrency systems. In currently existing cryptocurrencies, the blockchains used as transaction ledgers are never retired or archived, leading to increasingly-long block chains, and slow processing times in the peer-to-peer network, and increasing latencies. Two methods, in particular, may be used to retire or archive older portions of the blockchain, leaving a shorter blockchain as the active portion, and reducing latency times. First, a section closing method may be used wherein an entire blockchain for a certain period (for example, the previous year, as in year-end closing in accounting) is reconciled, the balances of each account (e.g., wallet) are moved to a new, shorter blockchain, and the old blockchain is archived. Second, an asynchronous closing method may be used wherein the old blockchain is kept open, but archived. A new blockchain is created, but account balances are not automatically transferred. Whenever an activity involves an entry in the old blockchain, that particular entry is consolidated and closed out from the old blockchain, and is transferred to the new blockchain. In this manner, the old blockchain will gradually be fully consolidated and closed out.

In some cases, a multi-tiered blockchain database may be used to implement a cryptocurrency system. Such an implementation may include one or more demarcated sections, or areas, in which transactions are limited to those of a lesser denomination, with a limited number of ledger transacting nodes and a limited number of gateways interacting between the general area of unlimited currency and the demarcated area. Such areas may have a limited-time active ledger, and older transactions are moved to an archive to speed up new transactions. In such cases, old wallet entries are then transferred at the time of use to a new section of a new ledger. Also, in that demarcated area, mining could be restricted. Further, in this area, a central issuer, or bank, with a reserve, may stabilize the currency, and currency in this area may be traded at a fixed rate to another currency in the same area, which may be a real currency rather on a major cryptocurrency. Additionally, in such areas, so called mixer wallets may be blocked or confiscated to avoid misuse of funds for illegitimate purposes.

In some embodiments, the implementation will include a number of standardized smart contracts to provide baseline support of some key functionality including coupons, timed escrow (pay after N days), key-based escrow, and other related functions. Providing a set of standardized smart contracts will mitigate the problem of an exploding world of poorly-written smart contracts in the same way careful design and engineering is required to effectively use stored procedures in modern databases.

In some embodiments, support may be included for anonymous messaging in the block chain. Such messaging may used to send basic messages between both parties as well as instructions to smart contracts. Such messages would be limited to text fields only, so as to eliminate a potential security hole where links and code (such as JavaScript) could be incorporated in messages for nefarious purposes.

In some embodiments, the wallets established for holding, tracking, and transferring valuation associated with entries in a blockchain database may be restricted to holding or tracking only valuation associated with a certain tier or tiers, a certain functional area or areas, a certain geographic area or areas, or any combination of these restrictions. In other embodiments, there may be no such restriction, and wallets would be allowed to hold, track, or transfer to or from a plurality of tiers, functional areas, or geographical areas. In some embodiments, wallets will allow users to see the value of their stored coinage in their native coin value or normalized to the wallet's default currency based on current market prices for valuation.

FIG. 1 (PRIOR ART) is a diagram illustrating the operation of existing cryptocurrencies using blockchain technology 100. A sender 101 initiates a transaction request 102, which includes the sender's digital signature 103, a deposit of a digital asset 104 such as an amount of cryptocurrency, and the recipient's public encryption key 105. The transaction request 102 is placed into a peer-to-peer distributed computing network 106 associated with this cryptocurrency, where it is timestamped, bundled into a block with other transactions and a hash of all previous blocks in the chain, and broadcast to all nodes 107 in the network 106. Each node 107 that receives the block 108 subjects it to repeated encryptions until a hash is found that has a certain number of zeros at the beginning, which serves as a confirmation of validity. Once the required hash is found for the block 108, the hash is broadcast back to the network 106 for confirmation by other nodes 107 in the network 106. When a threshold number of confirmations are obtained, the block 108 is permanently added to the blockchain 109, which serves as an unchangeable ledger of transactions. The transaction is completed, and the recipient 110 now owns the digital asset 104 deposited with the transaction request 102.

The nodes 107 typically hold copies of the blockchain, which acts as the ledger of a blockchain transaction. Also, the sender 101 and recipient 110 have digital wallets (not shown) that store information about their accounts. The complete details of blockchain transactions are not shown here, but they are well known in the art. Examples of cybercurrency currently using such an approach are Bitcoin, which has the bitcoin as the principal unit of currency and the satoshi, equal to 0.00000001 bitcoin. Another cybercurrency is the Ether (ETH), one of which is currently (mid July 2017) valued at approximately one-twelfth of a Bitcoin (BTC) and has approximately one million subunits. The problem, as mentioned above, is that it can take roughly half an hour to get a sufficient number of ledgers in a blockchain to execute a simple wallet transaction. For example, when a user wants to send an amount from one wallet to another, he needs to point to the address where his wallet keeps the bitcoin that he has currently with his private pointer and take the amount in that location. He then points to the payee and indicates the amount that he wants to send to the payee, retaining the rest for himself as the payor. The amount in that wallet location is split in two, with one amount sent to the payee and the remainder sent back to the payor. Such is the transaction in the blockchain, which can be publicly inspected. When a sufficient number of nodes in the blockchain community have accepted this transaction, it is considered fulfilled and transacted. The problem is that most participants who make such transactions, often for a small amount of satoshi, use most of the capacity for mining new bitcoin, so that mining is becoming increasingly more expensive. As a result, with the growing size of the ledger, the time for this transaction, waiting in queue and then actually executing, grows exceedingly long, leaving the cybercurrency involved in the transaction vulnerable to currency fluctuations. Also, mixer service or mixer wallets are sometimes used to anonymize currency. Many approaches exist and are known in the art.

Conceptual Architecture

The inventors have identified and eliminated these limits including reducing transaction latency and costs, micro payments that can be handled cost effectively, cracking the limits to growth, being a stable and localized store of value, coexisting with multiple cryptocurrencies, ease of use by the masses, and enhancing criminal deterrents.

What is clearly needed is a better system and method of executing cybercurrency transactions, especially for small transactions, to avoid such currency fluctuation risks and close transactions in a much shorter period of time.

In some cases, a limited amount of crypto currency may be sent by a message in form of an attached smart contract or credentials for accessing a cloud-based bot program. Further, certain contracts can temporarily be blocked from being active, pending a dispute resolution. Additionally, as part of the right to mine the top level coins, users agree to transact for free services in the lower levels, and a third party may be tasked to inspect and audit and act as an assurance entity for one or more regions of the crypto currency in return for a transaction fee in each region inspected and assured.

In a system where payments are done using tokens representing a currency, these tokens may be transacted on a blockchain and sometimes moved among banks, possibly resulting in an imbalance of bank FIAT accounts. In such cases, from time to time one or more banks may require a transfer on an RTGS system to correct an such an imbalance. In those cases where said RTGS system is not available during hours of non-operation, banks may move the RTGS transfer to a clearing house that is operational non-stop without any breaks, thus enabling settlements at any time of any day of the year. In some cases, to avoid complicated transfers of operations, such operations may always run via a clearing house. Further, the transfers to the clearing house are operated using the block chain network, to avoid any limitation of the RTGS time of operation. Additionally, should a particular bank's available balance on its FIAT account drop below a preset threshold, either the central bank or another pre-agreed partner will automatically launch an infusion of additional FIAT funds into the bank's account to maintain sufficient liquidity. Alternatively, rather than depending on a preset threshold, an AI system may be used to calculate the level upon which such an infusion is made, and also to calculate the required size of the infusion to stabilize the bank. In all such cases, one or more persons or institutions are notified at or shortly before such an event.

Detailed Description of Exemplary Aspects

FIG. 24 shows a point-of-sale (POS) transaction 2500 between a merchant phone (or other point of sale, or POS, device) 2501 and a buyer phone 2510, according to an aspect of the invention. Embedded in a quick response (QR) code 2502 (or in some cases other 2D barcode, or other enhanced barcodes, including but not limited to multi-dimensional or dynamic barcodes, dynamic barcodes with time signature, colored barcodes, any combination of the list etc.) are information sections 2503 a-n comprising additional information for different networks and payment information. During the transaction, the buyer's phone camera 2512 receives 2520 QR code 2502 and sends 2530 payment information 2511 to the merchant's phone via the network. (if no carrier or Wi-Fi network is available, other network methods can be employed, as discussed below.) The transaction is complete once the payment has been sent to the merchant's phone and shows up in his/her increased balance 2504. In other cases, any kind of barcodes may be sent to the merchant phone as evidence that the transaction has been made. In yet other cases the merchant device may not be a phone but a tablet or a notebook computer, a desktop computer, a modified cash register, or any other type of suitable computing device with software installed.

Alternatively, a secured transaction can be based on three-way optical interaction (P2P barcode). In this case, the buyer reads an encrypted dynamic (that is, one that may be changed every several seconds for security purposes) barcode (or QR code) with a time signature. The barcode or QR code represents a merchant identity or the merchant identity and additional transaction details (for example detailed list of groceries and their prices, as well as in some cases network information). The buyer validates (in a closed and trusted app) the merchant identity and transaction details and approves to send the required digital money from his wallet to the merchant. In those cases where there is no network available, the buyer may present an encrypted barcode to the merchant. The merchant then reads the barcode via the merchant wallet app (closed and trusted app) and validates the correctness of the transaction. The merchant sends approval via another encrypted barcode to the buyer that summarizes the transaction, so the two sides have both evidence and a receipt that the transaction has been completed. When the receipt of the merchant or the receipt of the buyer is sent and received on appropriate servers, the transaction may be added to a blockchain ledger and the transaction declared completed.

FIG. 23 shows an exemplary flow diagram 2400 of such a POS transaction, in which only the user side is shown. The transaction starts on the user side 2401 when he/she wants to buy a product. In the steps that follow, the user starts a transaction 2402, the camera activates to read the QR or 2D barcode 2403, and the camera extracts the payment and network information 2404.

Because there are multiple types of networking information embedded in the QR code, of interest is the specific networking information extracted in step 2404. The specific networking information may be used in step 2405, a decision tree that determines the best choice of network. For example, if the merchant and buyer have different phones (android versus iOS) a different type of network may be the appropriate choice compared to if both parties have the same phone. This is because certain types of networks only work between two phones with the same operating system versus two phones with different operating systems. Therefore, there are typically four P2P network options, including in some cases additionally near field communication or other suitable methods to choose from in step 2406 a-n, depending on the situation: direct Wi-Fi, ad hoc Wi-Fi, P2P Wi-Fi, P2P barcode and P2P Bluetooth, or any other suitable option. Other factors that influence network choice are whether the location has fixed Wi-Fi or whether the merchant is willing to share its Wi-Fi. If not, an ad-hoc P2P type network may be best. For example, in some cases, rather than using a traditional wireless local network, the two devices may exchange a series of at least two 2D barcodes or QR codes with each other, having the same net effect of conducting a private local data exchange. In some aspects, such private data exchanges are conducted using closed and trusted applications (apps) on each device that create and read dynamic, time dependent and encrypted 2d barcodes or QR codes.

Step 2407 a-n shows the different kinds of connection parameters necessary for each type of P2P network. If the connection fails during step 2408, the transaction loops back to step 2409 to try a different approach and select the next best connection parameter. If the connection succeeds during step 2408, the transaction continues on to step 2410. Step 2411 tests if the transaction is connected to the backbone. If not, both the merchant and buyer phones propagate the transaction (with increasing intervals) to other known, trusted devices in step 2413 until one of these devices connects to the backbone. If so, the transaction ends at step 2412.

This process 2400 protects merchants by ensuring buyers can't cheat or deny involvement in a transaction and vice versa. Buyers and sellers are accountable for their transactions because of step 2411, in which other devices can get an encrypted copy of this transaction, and any or all of them may then send this transaction to the backbone. (For example, even if the buyer throws away his device and claims to not have done the transaction, said transaction may have propagated through other devices to the backbone and still be registered.)

This process 2400 also ensures that the network can't be abused or used for personal gain. Because the network is only live for the duration of the transaction (a few seconds or minutes), and is not available after the transaction is completed, the user can't use it to download movies, for example. Also, in cases where the network only connects to the merchant's phone, instead of through to the backbone, the user won't have access to the Internet. In these cases the transaction is propagated to the backbone from the merchant's phone into the blockchain, etc.

Once a transaction has been sent to the backbone, it is added to the blockchain. Multiple copies may be added and should reconcile. If they don't, it may invoke a dispute resolution. Typically, offline transactions are limited in amount and numbers of transactions. Amount and number may vary depending on account balance and account history and offline rating and dispute history or lack thereof.

In systems where transactions are unable to connect to the backbone, the merchant phone and the buyer phone connect via an ad hoc network. Both phones keep a record of this transaction and make repeat attempts to send this information to the backbone. If neither phone can connect to the backbone, said phones will send an encrypted copy of their transaction to a known, trusted device on the network. This trusted device serves as a proxy and transmits the copied transaction to the backbone as soon as it is able to connect.

Some transactions may propagate in multiple paths from the non-connected area to the connected area, and third-party delivery may be much faster than the user's direct delivery. The multiple propagation paths may result not only from how reachable the network service originally was, but also about overloaded services and service availability. Examples of service disruption include high-service overload events such as concerts or shows (issues of service overload) and natural disasters (issues of service availability), where messages can only send from time to time instead of continuously and reliably.

In some cases a system for transacting in an environment without connectivity between a network backbone and a blockchain, a merchant device such as a phone or point of sale offers or transmits a set of credentials for an ad hoc network to close the transaction (by offering or transmitting an embedded set of optional ways to connect an ad hoc network between a buyer phone and a merchant phone or point of sale), and allows a direct exchange of multiple handshakes to secure the transaction, Both phones (or the consumer phone and the merchant phone and/or point of sale) will then keep a record of this transaction and try at the next opportunity to send this transaction over the network backbone to a blockchain. In yet other cases, each time such a client or merchant devices encounters other known, trusted devices on a P2P network, they may send an encrypted copy of their mutual transactions to the trusted devices, thereby enabling the encrypted copy to be transmitted over the network backbone to a blockchain as quickly as possible via repeated attempts by one or more trusted devices that may have better connectivity than the original sending device. A device that may or may not have been involved in the actual transaction may transmit the transaction to the network backbone and propagate it to the blockchain. Furthermore, in some cases, such client and/or merchant devices may be antitamper-hardened devices.

FIG. 3 is a diagram showing an exemplary system overview 400 of a multi-tiered blockchain database. In some embodiments, the blockchain database maintained for the global database 401, and for each lower tier database 402, 403 would comprise tiers of a single blockchain, but in other embodiments, they would comprise separate blockchains. In certain embodiments, the peer-to-peer networks for the global database 404 and for each lower tier region 406, 408 might be required to be separate and distinct (i.e., share no nodes 405, 407, 409), but in other embodiments might be allowed to share nodes 405, 407, 409. In some embodiments, there may exist gateway nodes 410, 411 between the global database 401 and each lower tier regional database 402, 403 to enforce separation of transactions in each region of each tier.

The machines that process transactions in these regions can process only in their own region, and only fractional transactions. Also, because only fractional transactions of fractional currency occur in these regions, no currency mining can occur, because no mining is allowed in these regions. If a user wants to change the currency, the currency is reserved via gateways 410 and 411 and blocked into the ledger in the main region and transferred into the lower region and made available as fractional currency. A small portion of that coin is then allocated to the operators of the ledger machines in each region, to pay operating costs. With no mining occurring in the regions, and with the regions being regionally limited in range, the cost of operation is much lower. Also, the local fractional currency could be, for example, bound to a local physical currency such as, for example, the U.S. dollar or the Euro, rather than to a cybercurrency such as Bitcoin or Ether, so there might be a local master currency available, issued by the conversion gateway, such as gateway 410 or 411, which would be paid for by currency in the upper domain and then actually converted by the gateways into a local physical currency. Those gateways might act as central banks, rather than as gateways, issuing a fractional currency only, and further in these regions there cannot be mining. Thus the transactions are faster and less vulnerable to currency fluctuations. Additionally, the ledgers may be split by years, with the current ledgers containing only transaction for the current year or two, and all previous transactions kept in archived ledgers, accessed only if a user has a wallet with an old balance. In such a case, as soon as the user wants to use the old balance, the wallet is retrieved from the archive, updated, and removed from the archive. Thus archived wallets may take a little longer to transact, but current wallets are much faster, because the ledger is kept current only in the ledger currency. Because the ledgers are regionalized, they can be much smaller and thus process transactions much more quickly. However, being regionalized does not mean a ledger is limited to one country. For example, in North America, each region could contain a piece of Canada, the United States, and Mexico. Thus, including multiple jurisdictions could avoid putting a region under the control of just one country. Wallets could simultaneously contain the physical currency of multiple regions, such as, for example, Euros, dollars, and yen. Most people spend currency in their home region, so merchants could execute transactions much more cheaply, because of the reduced risk of currency fluctuations in most cases.

Further, in some cases, when liquidity runs below a certain level, due to large outflow, a program or an AI module in the system can take at least one of several countermeasures: a) it can change exchange rate to reduce outflow, b) it can offer an interest for delaying a conversion, or c) it makes a cash call on certain members of a reserve group to allow a larger reserve to be built up quickly and thus maintain liquidity. This process can be triggered in an automated way by software and or an AI supervisory module (not shown) running as part of the management software of the system on at least one of the servers or as part of the EVM system (or similar) or both.

Various embodiments of the present disclosure may be implemented in computer hardware, firmware, software, and/or combinations thereof. Methods of the present disclosure can be implemented via a computer program instructions stored on one or more non-transitory computer-readable storage devices for execution by a processor. Likewise, various processes (or portions thereof) of the present disclosure can be performed by a processor executing computer program instructions. Embodiments of the present disclosure may be implemented via one or more computer programs that are executable on a computer system including at least one processor coupled to receive data and instructions from, and to transmit data and instructions to, a data storage system, at least one input device, and at least one output device. Each computer program can be implemented in any suitable manner, including via a high-level procedural or object-oriented programming language and/or via assembly or machine language. Systems of the present disclosure may include, by way of example, both general and special purpose microprocessors which may retrieve instructions and data to and from various types of volatile and/or non-volatile memory. Computer systems operating in conjunction with the embodiments of the present disclosure may include one or more mass storage devices for storing data files, which may include: magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and optical disks. Storage devices suitable for tangibly embodying computer program instructions and data (also called the “non-transitory computer-readable storage media”) include all forms of non-volatile memory, including by way of example semiconductor memory devices, such as EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM disks. Any of the foregoing can be supplemented by, or incorporated in, ASICs (application-specific integrated circuits) and other forms of hardware.

In some cases, a cryptocurrency system may include one or more demarcated sections, or areas, in which transactions are limited to those of a lesser denomination, with a limited number of ledger transacting nodes and a limited number of gateways interacting between the general area of unlimited currency and the demarcated area. Such areas may have a limited-time active ledger, and older transactions are moved to an archive to speed up new transactions. In such cases, old wallet entries are then transferred at the time of use to a new section of a new ledger. Also, in that demarcated area, no mining is allowed.

Further, in this area, a central issuer, or bank, with a reserve, may stabilize the currency, and currency in this area may be traded at a fixed rate to another currency in the same area, which may be a real currency rather on a major cryptocurrency. Additionally, in such areas, so called mixer wallets may be blocked or confiscated to avoid misuse of funds for illegitimate purposes.

Demarcated Block Sections

There are two possible methods to closing an active section of the blockchain. One is a pro-active, complete close, the other is a “on the fly, as you go” type close, performed asynchronously, as needed. Both are discussed below.

FIG. 4 is a diagram showing an exemplary method for improvement to blockchain databases: demarcated block sections 500, in which account reconciliation may be used to retire or archive older portions of the blockchain, leaving a shorter blockchain as the active portion, and reducing latency times. In the section closing method 510 the old blockchain 520 is reconciled all at once, and the balances of each account 540 are moved to a new, shorter blockchain 530, and the old blockchain 520 is archived. For example, when the old blockchain 520 is reconciled, account balance A 521 associated with account W1 541 and account balance B 522 associated with account W2 542 are moved to the new blockchain 530 simultaneously as account balance A 531 and account balance B 532, and the old blockchain 520 is archived. In the asynchronous closing method 550, the old blockchain 520 is kept open, but archived. A new blockchain 530 is created, but account balances are not automatically transferred. Whenever an activity involves an entry in the old blockchain 520, that entry is consolidated and closed out, and is transferred to the new blockchain 530. For example, entry D 524 has already been accessed, closed out, and transferred to the new blockchain 530. When entry C 523 associated with account W1 541 is accessed in the old blockchain 520, it will be closed out and transferred to the new blockchain 530. In this manner, the old blockchain 520 will gradually be fully consolidated and closed out.

FIG. 5 shows an exemplary multi-tiered blockchain database software architecture overview 600, according to an aspect of the invention. The basic system would comprise a plurality of user interfaces 601 through which users could manage their accounts, a series of contract managers 602, one for the global database, and one for each lower tier database, a series of blockchain engines 603, one for each database, and a series of local valuation managers 604 at the lower tiers only, which serve to fix the exchange rate of tokens within each region within the lower tier databases relative to another valuation in that region.

Two-Tier Coinage

FIG. 6 is a diagram showing an exemplary conceptual framework for a multi-tiered cryptocurrency 700. Tier 1 701 of the multi-tiered cryptocurrency would consist of a global cryptocurrency 702 with traits similar to existing cryptocurrencies 703 such as having currency generated over time, allowing mining, allowing the cryptocurrency to be traded as a security, and having a floating value. Other currencies could be exchanged for the global cryptocurrency through traditional banking means 704. Tier 2 705 would likely be regional or national in scope. The cryptocurrency at this tier would be converted from the global cryptocurrency 702, and would have traits different from existing cryptocurrencies 706 that facilitate small value transactions, such as no mining ability, not tradeable as securities, and value tied to a local real currency. In one embodiment, one Tier 2 705 cryptocurrency could be restricted to use in the United States with the value tied to value the US dollar 707 with transactions limited in value and optimized for small local transactions such as fast food or gas purchases 708, while another Tier 2 705 tier cryptocurrency could be restricted to use in Europe with the value tied to the Euro 709, with transactions limited in value and optimized for small local transactions such as fast food or gas purchases 710. For clarity and simplicity, only two exemplary regions are shown, but there could well exist many more. The first- or “top-tier” coin 701 is a generated coin—there will only be a limited number ever minted. It is the primary vehicle for monetary exchange and these coins contain all of the value in the system, except what is contained in the locally-valued second tier coins 705. These second-tier coins 705 are also generated and are created when money moves into a local currency and are “destroyed” or invalidated when the money exits the system to the first-tier 701 or is cashed out of the system. The second-tier coin 705 is also backed by a local agency or bank to stabilize the value of the second-tier country-specific currency. In order to incentivize the local agencies, they will be allowed (under strict guidelines) to hold a portion of the funds in first-tier coinage 701 or utilize a portion of the funds for other activities. They will also have the option of insuring the value of the currency tied to second-tier coin 705 and charge a fee to the users for that insurance.

Fees and Revenue

The present invention may charge a small fee every time a coin is moved. FIGS. 7 and 8 are an exchange flow diagrams 800, 900 indicating where fees may be charged. Referring to FIG. 7 , fees may be incurred during purchase of first-tier coin 801, sale of first-tier coin 802, and transferring funds from one wallet to another 803.

FIG. 8 is a diagram showing an exemplary fee and revenue structure 900 for a multi-tiered cryptocurrency. Operating revenue for the multi-tiered cryptocurrency would be provided by charging a small fee each time currency is moved anywhere in the system, including, for example, purchase of the global cryptocurrency 901 using traditional currencies, sale of the global cryptocurrency 902 back to traditional currencies, conversion of the global cryptocurrency to lower tier cryptocurrencies 903, conversion of a lower tier cryptocurrency back to the global cryptocurrency 904, payments to merchants using a lower tier cryptocurrency 905, transfers to wallets 906, transfers between wallets 907, and transfers from wallets 908.

Single-Use Cryptocurrency

Single-use coin in the second-tier coins enables the control and tracking of currency in a public blockchain with no storage of value. These single use coins are created then destroyed after redemption, unlike classic cryptocurrency where coins have an infinite lifespan. They are also used for other one-time transactions or other applications where value is held on a one time basis or time-limited. For example, a company may provide “expiring cash offers”, where a specific amount of currency is credited to a specific individual but expires at a specific time or because of a specific event. No equivalent of this function exists within current cryptocurrency solutions. Destruction of these coins via smart contracts and directly via the blockchain yields significantly enhanced security to this cryptocurrency solution.

Single-Use Cryptocurrency

To provide single-use cryptocurrency capability, the present invention includes an expanded address space so it is effectively infinite, which allows this functionality to work for hundreds of years without running out of capacity.

FIG. 9 is a diagram showing an exemplary technical improvement to blockchain databases: extended address space 1000. Current blockchains use a 256-bit address space 1001. While this is sufficient for existing blockchains with infinite token lifespan (e.g. Bitcoin, Ethereum), 256 bits is insufficient for use of single-use token technology, where the creation and destruction of each coin must be recorded. This would saturate the existing 256-bit address space, degrading performance and eventually rendering the blockchain and cryptocurrency useless. The solution is to use an address space extension 1002, comprised of a descriptive address header 1003, and an n-bit prefix 1004, which effectively provides unlimited address space.

Leveraging Standardized Contracts

The present invention includes support for what is known as “smart contract” functionality, which may be found in core Ethereum, but will also be released with a number of standardized contract to provide baseline support of some key functionality including coupons, timed escrow (pay after N days), key-based escrow, and other related functions.

Providing a set of standardized contracts will mitigate the problem of an exploding world of poorly-written smart contracts in the same way careful design and engineering is required to effectively use stored procedures in modern databases.

In-Transaction Messaging

The present invention includes support for carefully limited anonymous messaging in the block chain. It is used to send basic messages between both parties as well as messages to Smart Contracts. It exists only as a text field and cannot be executed directly. This is done in order to eliminate a potential security hole where links and code (such as JavaScript) can be incorporated in messages for nefarious purposes.

Wallet Integrations and Ease-of-Use

The present invention may integrate first-tier and second-tier coin within many coin wallets, and included an enhanced wallet that allows coin value to be moved from first-tier and various denominations of second-tier coins. In addition, the enhanced will allow users to see the value of their stored coinage in their native coin value or normalized to the wallet's default currency based on current market prices for coin.

FIG. 14 shows an overview of an exemplary high-performance scalability test configuration, according to one aspect of the system and method disclosed herein. Typically, a cluster would run on a cloud system, for example Amazon Web Service (AWS), so the effort is minimal. By launching a command, all the instances are automatically created. Next, the user gets access to a control console, such as window 1500. There he can set the number of nodes 1501 a N(m) by setting value M in the box B (top right)—the system then adjusts the number of nodes appearing on the screen accordingly. Value M is limited to a “reasonable, feasible” range (cost, performance) in this example. Also, the number of clients 1503 a C(r) may, for a typical test, range from 5-13, but that number can be adjusted by changing value R in the box (top right) within a range beyond that. Each client 1503 b adds a certain demand on the network, resulting in a system total transaction throughput that may be measured, for example, by a performance gauge (not shown here), which gauge should be like a speedometer showing millions of transactions per second (MTPS). If a node 1501 d is taken off line by a user, or connections are shut off, clients on that node are moved to other nodes 1501 e, 1501 b to keep the system load the same. Users can mouse over a node such as, for example, node 1509 and see a panel with details, allowing a user or tester to shut down a node or turn it back on. The same approach may be applied for clients 1505 and links in the network, or nodes deeper in the network 1501 c.

Further, while looking at details of a node, such as node 1509, a user can click a login information link and open a new window 1506 to see what is happening in detail inside the node, for example on the blockchain 1507 a-n. An analogous approach for clients 1505 would result in multiple additional terminal windows.

FIG. 15 shows an exemplary testing system 1600, according to one aspect of the system and method disclosed herein. System 1600, in this case, encompasses a single local token area 1601, using, in this example, Euro tokens 1604. Further, system 1600 is based on pre-generated accounts (wallets) W1 1602 and W2 1603, and is has a set of pre-generated transactions (not shown) to operate on. According to the article “Cryptocurrency Wallet Guide: A Step-By-Step Tutorial,” at https://blockgeeks.com/guides/cryptocurrency-wallet-guide/, “A cryptocurrency wallet is a software program that stores private and public keys and interacts with various blockchain to enable users to send and receive digital currency and monitor their balance. If you want to use Bitcoin or any other cryptocurrency, you will need to have a digital wallet.”

For the infrastructure and pre-generated datasets, there would be, for example, five nodes, at a minimum, in a private Ethereum-based network in the AWS cloud. Pre-generated ad re-usable datasets could comprise 10,000 accounts (wallets), where each wallet holds a random number of tokens between 10 and 1000. In a simplified view such as FIG. 16 , for example, several wallets such as, for example, exemplary wallets W1 1602 and W2 1603 are shown in a region 1601 that contains EUR type tokens 1604. The proof of scope concept border 1601 is limited to that area, and would, in this example, not include Global tokens 1605, USD tokens 1606 or other instrument tokens such as VISA or MC tokens 1607, etc. Wallet A (for example W1) could have N tokens. For each set of 1,000,000 transactions, the system would transfer N tokens from wallet A (W1) to wallet B W2 or similar via arrow 1608, but not amongst different token areas initially.

In the implementation phases, the goal for each phase is to measure performance. Performance may be defined as N transactions/seconds (TPS), with the TPS stable after M seconds.

In phase one of building such a system, a minimum five-node Ethereum network is established on AWS. Then datasets are pre-generated in a database, such as, for example, Mongo database. Programs to generate accounts and wallets with tokens in Ethereum and to pre-load transactions in Ethereum queues without executing them are created. Transaction in out-of-box Ethereum are executed, and performance is measured. The test run may be stopped after the TPS becomes stable. Then the test run and measurements are repeated using a 15-node Ethereum network.

In phase two, users would decrease the Ethereum block time to six seconds, run transactions, and measure performance. Testing would be repeated, decreasing the Ethereum block time further, running transactions, and measuring performance, until we the minimum viable block time is established.

It is expected that Phase 1 and 2 should be completed in 2 weeks from start.

Phase three runs in parallel to phases one and two. In phase three, the crypto puzzle is replaced with alternative puzzles such as a trust puzzle that is much simple and faster, enabling the TPS to increase dramatically. Transactions are run in iterations, and performance is measured.

Phase four requires additional implementation of demarcated blockchains. Again, this phase runs in parallel to phases one and two. Transactions are run in iterations, and performance is measured.

Phase five comprises establishment of shared blockchains. Again, this phase runs in parallel to phases one, two, and three. Transactions are run in iterations, and performance is measured.

FIG. 16 shows a simplified version of an exemplary typical in-country network 1700, according to one aspect of the system and method known to inventors. Network 1700 includes in-country (or regional) private blockchain network 1709, which is connected to multiple banks 1701 a-n. Network 1709 may, in some cases, be a virtual network. It also shows an exemplary national bank (NB) 1712 (or regional lead bank), at least one (in some cases more) auditor company or institution (ACI) 1715, and a preferred system provider (PSP) 1705. In some cases, the owner of the master key can give different auditors different rights, such as limited-read only rights, limited sections, limited scope or time audits, etc. In the example shown in FIG. 17 , each bank has at least one primary server 1702 a-n. Similarly, PSP 1705 has server 1706, NB 1712 has server 1713, and ACI 1715 has server 1716. All these servers are connected to private blockchain network 1709. Gateways, such as 1717, 1714, and 1704 a-n, connect to public Internet 1710, as does gateway 1707, which enables the general public to interact with the banks and auditor ACI. Not shown in detail are all the internal firewalls, backups, and additional servers that typically exist. Also, often a bank may have facilities in multiple locations, and in larger countries or regions banks may have multiple servers in different areas connected in separate locations to the network for redundancy (also not shown for simplicity). In some cases, the NB may not want initially to start to become active in the currency system, so the PSP may initially hold the master key for security of the network. In other cases, for legal reasons, the ACI may hold this key, as a legal, local entity. Once the NB feels comfortable taking on a leading role, it can request or legally demand the master key and house it on their servers henceforth. Additionally, upper network 1711 is for international transactions. It has separate gateways 1703 a-n in each bank, as well as gateway 1708 for preferred provider 1705. In this example, national bank 1712 and auditor 1715 do not have a connection to upper network 1711, since they don't engage in international transactions on network 1711 for the upper level token. In other cases, they may participate as well.

FIG. 17 shows an exemplary network 1800, according to one aspect of the system and method disclosed herein. In addition to the national and international networks shown in FIG. 17 , described above, an exemplary classic network is present, comprising clouds 1801 a-n, such as existing IBAN, ACH, SWIFT, and other existing international transfer networks for interbank transfers, both national and international, typically so called real time gross settlement (RTGS) networks. These RTGS networks 1804 a-n can be integrated into such a system, with gateways in each separate bank 1803 a, 1803 b, 1803 n, including one gateway for a national or regional lead bank 1802, so they can complement the money flow.

Further, digital (token) wallets for this multi-bank retail blockchain (not shown) can enable, via API, integration of existing banking apps and wallet apps, so a user can operate all his accounts and transactions from one location.

FIG. 18 shows an exemplary system 1900 connecting banks, customers, and clearing houses, according to one aspect of the system and method disclosed herein. Banks 1901 a through 1901 n are connected to a real-time gross settlement (RTGS) network 1910 that is connected, in this example, to central bank 1911 but other RTGS systems may also exist and may be connected to those and other banks. Central bank 1911 may have attached nostro/vostro accounts 1912 a-n. Each bank may have a connection 1906 a-n to blockchain 1906, to which may be attached to customer handsets 1904 a through 1904 n via connections 1903 a through 1903 n. Further, each handset may contain software 1905 aa-n through 1905 na-n. In this example, this software includes an operating system, other applications, and the application to operate the bank account on the blockchain, for the purpose of making transfers and other money-management operations.

As money is moved among various different banks on the blockchain, typically by users transacting on the above-mentioned handsets acting as mobile wallets, money between the FIAT pools 1902 a through 1902 n needs to be moved between banks periodically to reflect the motion of tokens on the blockchain, either because the difference between tokens and FIAT between banks has grown too large, during or at the end of the day. Such moves are typically done through the RTGS network 1910. However, currently in the United States, the federal reserve shuts down such activities at night, during the weekend, and on holidays. In many other countries RTGS systems shut down in similar manner as in the United States. Thus, during such periods of enforced inactivity, a large imbalance may occur, and there is even the theoretical possibility of a bank becoming illiquid because more money has gone out than the bank owns. As an alternative solution, central bank 1911 may keep an account, such as account 1913, open at all times, 24/7/365, as well as operate at least part of RTGS 1910 accordingly. Or, if the bank is unwilling to operate around the clock, the central bank may hold the FIAT money in accounts such as account 1913, during hours of inactivity, and update the FIAT pools correctly at the next instance of activity based on the status reported from blockchain. Alternatively, at least one clearing house, such as clearing house 1921 (only one shown), may keep a special account, such as account 1922 (only one shown), open during the hours when banks are not open, that is, nights, weekends, holidays, or as a normal transaction vehicle for FIAT transactions among banks. In that case, banks would transfer, for example, all their balances every 10 or 15 minutes, or even every 5 minutes, depending on their volume, frequency of transactions, imbalances, and other triggers as desired or required, into or from the clearing house. Thus the clearing house plays the role of a trusted third party, similar to the central bank, as the clearing house has relationships 1920 with most, if not all, banks, and is a trusted, licensed player in the banking system. A clearing house can take over this role easily, and most clearing houses today operate 24/7/365, because they have this transaction capability for the stock exchanges. Hence, they can offer, for a small fee, to do FIAT transactions for the banks. These transaction can be done in a single account or they could be done as subaccounts for each bank, in which case the clearing could happen locally. Thus the balances could be always reflected correctly, 24/7, and FIAT balances could be operated correctly, no matter whether the central bank is available or not. In places where there is no central bank and no clearing houses, a third party could be used to provide clearing bank services. In some cases, these FIAT transaction could be operated over the blockchain network rather than over the regular RTGS network.

In some cases, banks linked in a private network, which in some cases may be a virtual private network, may participate in transactions made on behalf of their retail customers on a retail-oriented blockchain. In addition, a supervisory bank or agency may participate in this private network, so that in certain cases this supervisory party may exert its supervisory power under a contractual agreement. These banks may also participate in a second private network for blockchain transactions, which network may be used for interbank and international transactions. Furthermore, a preferred Internet provider may be connected to the banks' private network. This provider may hold the master security certificate for operating the private network, or it may transfer the master security certificate to the supervisory bank or agency, thus making the recipient of the master certificate the future provider of the master security certificate. In other cases, a non-transacting auditor may also connected to the private network. The holder of the master key may be located in the private network, linked with its own computing device on the blockchain, enabling auditors to have various levels of access rights, including but not limited to section-limited, read-only limited, time- or time-period limited, etc. access to the blockchain via certificate and network access for audit and review purposes under a contractual agreement.

In a system where payments are done using tokens representing a currency, these tokens may be transacted on a blockchain and sometimes moved among banks, possibly resulting in an imbalance of bank FIAT accounts. In such cases, from time to time one or more banks may require a transfer on an RTGS system to correct a such an imbalance. In those cases where said RTGS system is not available during hours of non-operation, banks may move the RTGS transfer to a clearing house that is operational non-stop without any breaks, thus enabling settlements at any time of any day of the year. In some cases, to avoid complicated transfers of operations, such operations may always run via a clearing house. Further, the transfers to the clearing house are operated using the block chain network, to avoid any limitation of the RTGS time of operation. Additionally, should a particular bank's available balance on its FIAT account drop below a preset threshold, either the central bank or another pre-agreed partner will automatically launch an infusion of additional FIAT funds into the bank's account to maintain sufficient liquidity. Alternatively, rather than depending on a preset threshold, an AI system may be used to calculate the level upon which such an infusion is made, and also to calculate the required size of the infusion to stabilize the bank. In all such cases, one or more persons or institutions are notified at or shortly before such an event.

In various aspects, functionality for implementing systems or methods of various aspects may be distributed among any number of client and/or server components. For example, various software modules may be implemented for performing various functions in connection with the system of any particular aspect, and such modules may be variously implemented to run on server and/or client components.

Referring generally to FIG. 19 , in which an enhanced system and method of conducting international trading transactions is shown and comparing to the example described in the Background section, a new example analogous to example 1 will illustrate the benefits of a novel aspect. In this case, the issue is trading spot US$ and Liquineq Global tokens (LG; note this is exemplary, and other crypto tokens could be traded according to the aspect) to euros (€), as a spread with only 1 bid/ask:

-   -   1—Trader A 2001 sells US$2002 and buys L-US$2004 1 to 1 no         bid/ask crossed     -   2&3—Trader A Sells L-US$ & buys LG 2003 and as part of the same         trade with         the same counterparty sells LG and buys L-euro (L€), all as one         spread trade.

In the example, The LGs either net out as they trade, or they act as a hedge of the L currencies at the same price for the buy and sell. Any “know your customer” (KYC) or other regulatory certificates are added as necessary into the transaction.

In those cases where there are regulatory issues with the LGs needing to be actually transferred rather than netted, traders would need to inventory a small amount of LG to facilitate these spread trades.

In this system for transacting multiple payment tokens on a blockchain, it has at least one processor, but typically many more, often in the cloud, or in different location for redundancy and security. Application software running on that system (meaning on at least one of the processors) allows one to perform the steps of a transaction consisting of listing a first trader buying an intermediary token with a first currency with the intent to buy a second currency, finding at least one second trader willing to sell a matching amount of said second currency sought by first trader against said intermediary token, and once a price has been agreed upon, a transaction is closed. Further, in some cases, the step of the intermediary token is explicit. Furthermore, in other cases the step of the intermediary token is eliminated after the regulatory needs have been met. In yet other cases after the transaction closes the intermediary token in immediately re-used in a new transaction thereafter.

FIG. 20 shows a simplified diagram of a cold storage facility or bank that can be used to store crypto currencies to make quick raids more difficult, according to an aspect. According to the aspect, 2101 a . . . n are at least one, often many un-permissioned blockchains of the different cryptocurrencies; 2102 a . . . n for example are airgap switches with buffers (other equivalent systems and methods of insulation can be used), that can be used to allow selectively content from a wallet to be transferred via a buffer into cold storage unit 2103 aa . . . nn, which has many addressable compartments at least one for each customer 2105.

FIG. 21 shows a simplified diagram of a novel approach how to enable usage while crypto currencies are in cold storage, according to an embodiment. It shows an inventory management section 2201, which helps review and manage the content of cold storage 2103 aa . . . nn. That information can be used by eToken issuance section 2202 to issue for those cryptocoins that the users have allowed eTokens, that can be used for all practical purposes like real cryptocurrencies, but much faster and more securely. To do that, user management section 2203 allows those tokens to be sent to the correct user wallets such as exemplary user wallet 2204 x, which shares connection to the unpermissioned blockchain 2205 along with possible other wallets 2204 h and allows them to be used like regular eMoney in real time, with fast settlement; but, rather than being backed by fiat money, this one is back by cryptocurrency. After the transactions are completed, the cryptos can be settled cold storage to cold storage, without putting the real cryptos at any peril or delays for settlement.

FIG. 22 shows a simplified diagram of a software used to take cryptos into a novel type cold storage that allows for continued use of stored crypto currencies. After initiating the process 2301, as part of a first operational step 2302 the wallet is selected from which the crypto is deposited. In step 2303 the process of passing through the airgap switch into cold storage is performed, and the information is noted in general storage 2304, which is part of inventory management 2201 described earlier. The user now can choose if to just store (draw e-crypto) in step 2305 (no) or use e-crypto (yes). In first case the flow continues to 2308 to end. In latter case it continues to 2306 to issue a matching number of e-cryptos (or in some cases only partial amount). In step 2307 those cryptos are then moved via user management 2203 to the users wallet. It then ends in step 2308.

Once the user spends his e-cryptos, full or fractional crypto tokens are settled via the non-permissioned blockchains with the respective parties. Since the user had to use his more secure wallet, only authorized transactions will be enabled and cleared.

Hardware Architecture

Generally, the techniques disclosed herein may be implemented on hardware or a combination of software and hardware. For example, they may be implemented in an operating system kernel, in a separate user process, in a library package bound into network applications, on a specially constructed machine, on an application-specific integrated circuit (ASIC), or on a network interface card.

Software/hardware hybrid implementations of at least some of the aspects disclosed herein may be implemented on a programmable network-resident machine (which should be understood to include intermittently connected network-aware machines) selectively activated or reconfigured by a computer program stored in memory. Such network devices may have multiple network interfaces that may be configured or designed to utilize different types of network communication protocols. A general architecture for some of these machines may be described herein in order to illustrate one or more exemplary means by which a given unit of functionality may be implemented. According to specific aspects, at least some of the features or functionalities of the various aspects disclosed herein may be implemented on one or more general-purpose computers associated with one or more networks, such as for example an end-user computer system, a client computer, a network server or other server system, a mobile computing device (e.g., tablet computing device, mobile phone, smartphone, laptop, or other appropriate computing device), a consumer electronic device, a music player, or any other suitable electronic device, router, switch, or other suitable device, or any combination thereof. In at least some aspects, at least some of the features or functionalities of the various aspects disclosed herein may be implemented in one or more virtualized computing environments (e.g., network computing clouds, virtual machines hosted on one or more physical computing machines, or other appropriate virtual environments).

Referring now to FIG. 10 , there is shown a block diagram depicting an exemplary computing device 10 suitable for implementing at least a portion of the features or functionalities disclosed herein. Computing device 10 may be, for example, any one of the computing machines listed in the previous paragraph, or indeed any other electronic device capable of executing software- or hardware-based instructions according to one or more programs stored in memory. Computing device 10 may be configured to communicate with a plurality of other computing devices, such as clients or servers, over communications networks such as a wide area network a metropolitan area network, a local area network, a wireless network, the Internet, or any other network, using known protocols for such communication, whether wireless or wired.

In one aspect, computing device 10 includes one or more central processing units (CPU) 12, one or more interfaces 15, and one or more busses 14 (such as a peripheral component interconnect (PCI) bus). When acting under the control of appropriate software or firmware, CPU 12 may be responsible for implementing specific functions associated with the functions of a specifically configured computing device or machine. For example, in at least one aspect, a computing device 10 may be configured or designed to function as a server system utilizing CPU 12, local memory 11 and/or remote memory 16, and interface(s) 15. In at least one aspect, CPU 12 may be caused to perform one or more of the different types of functions and/or operations under the control of software modules or components, which for example, may include an operating system and any appropriate applications software, drivers, and the like.

CPU 12 may include one or more processors 13 such as, for example, a processor from one of the Intel, ARM, Qualcomm, and AMD families of microprocessors. In some aspects, processors 13 may include specially designed hardware such as application-specific integrated circuits (ASICs), electrically erasable programmable read-only memories (EEPROMs), field-programmable gate arrays (FPGAs), and so forth, for controlling operations of computing device 10. In a particular aspect, a local memory 11 (such as non-volatile random access memory (RAM) and/or read-only memory (ROM), including for example one or more levels of cached memory) may also form part of CPU 12. However, there are many different ways in which memory may be coupled to system 10. Memory 11 may be used for a variety of purposes such as, for example, caching and/or storing data, programming instructions, and the like. It should be further appreciated that CPU 12 may be one of a variety of system-on-a-chip (SOC) type hardware that may include additional hardware such as memory or graphics processing chips, such as a QUALCOMM SNAPDRAGON™ or SAMSUNG EXYNOS™ CPU as are becoming increasingly common in the art, such as for use in mobile devices or integrated devices.

As used herein, the term “processor” is not limited merely to those integrated circuits referred to in the art as a processor, a mobile processor, or a microprocessor, but broadly refers to a microcontroller, a microcomputer, a programmable logic controller, an application-specific integrated circuit, and any other programmable circuit.

In one aspect, interfaces 15 are provided as network interface cards (NICs). Generally, NICs control the sending and receiving of data packets over a computer network; other types of interfaces 15 may for example support other peripherals used with computing device 10. Among the interfaces that may be provided are Ethernet interfaces, frame relay interfaces, cable interfaces, DSL interfaces, token ring interfaces, graphics interfaces, and the like. In addition, various types of interfaces may be provided such as, for example, universal serial bus (USB), Serial, Ethernet, FIREWIRE™, THUNDERBOLT™, PCI, parallel, radio frequency (RF), BLUETOOTH™, near-field communications (e.g., using near-field magnetics), 802.11 (WiFi), frame relay, TCP/IP, ISDN, fast Ethernet interfaces, Gigabit Ethernet interfaces, Serial ATA (SATA) or external SATA (ESATA) interfaces, high-definition multimedia interface (HDMI), digital visual interface (DVI), analog or digital audio interfaces, asynchronous transfer mode (ATM) interfaces, high-speed serial interface (HSSI) interfaces, Point of Sale (POS) interfaces, fiber data distributed interfaces (FDDIs), and the like. Generally, such interfaces 15 may include physical ports appropriate for communication with appropriate media. In some cases, they may also include an independent processor (such as a dedicated audio or video processor, as is common in the art for high-fidelity AN hardware interfaces) and, in some instances, volatile and/or non-volatile memory (e.g., RAM).

Although the system shown in FIG. 10 illustrates one specific architecture for a computing device 10 for implementing one or more of the aspects described herein, it is by no means the only device architecture on which at least a portion of the features and techniques described herein may be implemented. For example, architectures having one or any number of processors 13 may be used, and such processors 13 may be present in a single device or distributed among any number of devices. In one aspect, a single processor 13 handles communications as well as routing computations, while in other aspects a separate dedicated communications processor may be provided. In various aspects, different types of features or functionalities may be implemented in a system according to the aspect that includes a client device (such as a tablet device or smartphone running client software) and server systems (such as a server system described in more detail below).

Regardless of network device configuration, the system of an aspect may employ one or more memories or memory modules (such as, for example, remote memory block 16 and local memory 11) configured to store data, program instructions for the general-purpose network operations, or other information relating to the functionality of the aspects described herein (or any combinations of the above). Program instructions may control execution of or comprise an operating system and/or one or more applications, for example. Memory 16 or memories 11, 16 may also be configured to store data structures, configuration data, encryption data, historical system operations information, or any other specific or generic non-program information described herein.

Because such information and program instructions may be employed to implement one or more systems or methods described herein, at least some network device aspects may include nontransitory machine-readable storage media, which, for example, may be configured or designed to store program instructions, state information, and the like for performing various operations described herein. Examples of such nontransitory machine-readable storage media include, but are not limited to, magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROM disks; magneto-optical media such as optical disks, and hardware devices that are specially configured to store and perform program instructions, such as read-only memory devices (ROM), flash memory (as is common in mobile devices and integrated systems), solid state drives (SSD) and “hybrid SSD” storage drives that may combine physical components of solid state and hard disk drives in a single hardware device (as are becoming increasingly common in the art with regard to personal computers), memristor memory, random access memory (RAM), and the like. It should be appreciated that such storage means may be integral and non-removable (such as RAM hardware modules that may be soldered onto a motherboard or otherwise integrated into an electronic device), or they may be removable such as swappable flash memory modules (such as “thumb drives” or other removable media designed for rapidly exchanging physical storage devices), “hot-swappable” hard disk drives or solid state drives, removable optical storage discs, or other such removable media, and that such integral and removable storage media may be utilized interchangeably. Examples of program instructions include both object code, such as may be produced by a compiler, machine code, such as may be produced by an assembler or a linker, byte code, such as may be generated by for example a JAVA™ compiler and may be executed using a Java virtual machine or equivalent, or files containing higher level code that may be executed by the computer using an interpreter (for example, scripts written in Python, Perl, Ruby, Groovy, or any other scripting language).

In some aspects, systems may be implemented on a standalone computing system. Referring now to FIG. 11 , there is shown a block diagram depicting a typical exemplary architecture of one or more aspects or components thereof on a standalone computing system. Computing device 20 includes processors 21 that may run software that carry out one or more functions or applications of aspects, such as for example a client application 24. Processors 21 may carry out computing instructions under control of an operating system 22 such as, for example, a version of MICROSOFT WINDOWS™ operating system, APPLE macOS™ or iOS™ operating systems, some variety of the Linux operating system, ANDROID™ operating system, or the like. In many cases, one or more shared services 23 may be operable in system 20, and may be useful for providing common services to client applications 24. Services 23 may for example be WINDOWS™ services, user-space common services in a Linux environment, or any other type of common service architecture used with operating system 21. Input devices 28 may be of any type suitable for receiving user input, including for example a keyboard, touchscreen, microphone (for example, for voice input), mouse, touchpad, trackball, or any combination thereof. Output devices 27 may be of any type suitable for providing output to one or more users, whether remote or local to system 20, and may include for example one or more screens for visual output, speakers, printers, or any combination thereof. Memory 25 may be random-access memory having any structure and architecture known in the art, for use by processors 21, for example to run software. Storage devices 26 may be any magnetic, optical, mechanical, memristor, or electrical storage device for storage of data in digital form (such as those described above, referring to FIG. 10 ). Examples of storage devices 26 include flash memory, magnetic hard drive, CD-ROM, and/or the like.

In some aspects, systems may be implemented on a distributed computing network, such as one having any number of clients and/or servers. Referring now to FIG. 12 , there is shown a block diagram depicting an exemplary architecture 30 for implementing at least a portion of a system according to one aspect on a distributed computing network. According to the aspect, any number of clients 33 may be provided. Each client 33 may run software for implementing client-side portions of a system; clients may comprise a system 20 such as that illustrated in FIG. 12 . In addition, any number of servers 32 may be provided for handling requests received from one or more clients 33. Clients 33 and servers 32 may communicate with one another via one or more electronic networks 31, which may be in various aspects any of the Internet, a wide area network, a mobile telephony network (such as CDMA or GSM cellular networks), a wireless network (such as WiFi, WiMAX, LTE, and so forth), or a local area network (or indeed any network topology known in the art; the aspect does not prefer any one network topology over any other). Networks 31 may be implemented using any known network protocols, including for example wired and/or wireless protocols.

In addition, in some aspects, servers 32 may call external services 37 when needed to obtain additional information, or to refer to additional data concerning a particular call. Communications with external services 37 may take place, for example, via one or more networks 31. In various aspects, external services 37 may comprise web-enabled services or functionality related to or installed on the hardware device itself. For example, in one aspect where client applications 24 are implemented on a smartphone or other electronic device, client applications 24 may obtain information stored in a server system 32 in the cloud or on an external service 37 deployed on one or more of a particular enterprise's or user's premises.

In some aspects, clients 33 or servers 32 (or both) may make use of one or more specialized services or appliances that may be deployed locally or remotely across one or more networks 31. For example, one or more databases 34 may be used or referred to by one or more aspects. It should be understood by one having ordinary skill in the art that databases 34 may be arranged in a wide variety of architectures and using a wide variety of data access and manipulation means. For example, in various aspects one or more databases 34 may comprise a relational database system using a structured query language (SQL), while others may comprise an alternative data storage technology such as those referred to in the art as “NoSQL” (for example, HADOOP CASSANDRA™, GOOGLE BIGTABLE™, and so forth). In some aspects, variant database architectures such as column-oriented databases, in-memory databases, clustered databases, distributed databases, or even flat file data repositories may be used according to the aspect. It will be appreciated by one having ordinary skill in the art that any combination of known or future database technologies may be used as appropriate, unless a specific database technology or a specific arrangement of components is specified for a particular aspect described herein. Moreover, it should be appreciated that the term “database” as used herein may refer to a physical database machine, a cluster of machines acting as a single database system, or a logical database within an overall database management system. Unless a specific meaning is specified for a given use of the term “database”, it should be construed to mean any of these senses of the word, all of which are understood as a plain meaning of the term “database” by those having ordinary skill in the art.

Similarly, some aspects may make use of one or more security systems 36 and configuration systems 35. Security and configuration management are common information technology (IT) and web functions, and some amount of each are generally associated with any IT or web systems. It should be understood by one having ordinary skill in the art that any configuration or security subsystems known in the art now or in the future may be used in conjunction with aspects without limitation, unless a specific security 36 or configuration system 35 or approach is specifically required by the description of any specific aspect.

FIG. 13 shows an exemplary overview of a computer system 40 as may be used in any of the various locations throughout the system. It is exemplary of any computer that may execute code to process data. Various modifications and changes may be made to computer system 40 without departing from the broader scope of the system and method disclosed herein. Central processor unit (CPU) 41 is connected to bus 42, to which bus is also connected memory 43, nonvolatile memory 44, display 47, input/output (I/O) unit 48, and network interface card (NIC) 53. I/O unit 48 may, typically, be connected to keyboard 49, pointing device 50, hard disk 52, and real-time clock 51. NIC 53 connects to network 54, which may be the Internet or a local network, which local network may or may not have connections to the Internet. Also shown as part of system 40 is power supply unit 45 connected, in this example, to a main alternating current (AC) supply 46. Not shown are batteries that could be present, and many other devices and modifications that are well known but are not applicable to the specific novel functions of the current system and method disclosed herein. It should be appreciated that some or all components illustrated may be combined, such as in various integrated applications, for example Qualcomm or Samsung system-on-a-chip (SOC) devices, or whenever it may be appropriate to combine multiple capabilities or functions into a single hardware device (for instance, in mobile devices such as smartphones, video game consoles, in-vehicle computer systems such as navigation or multimedia systems in automobiles, or other integrated hardware devices).

FIG. 2 shows an exemplary overview of a standard cloud computing infrastructure, according to an aspect. Server 302 may be a single physical server, or it may be a cluster 303 of many smaller servers 304 a-n. These servers can contain multiple sets of codes 305 a-n, including multiple operating systems, on top of which may be multiple applications 306 a-n and additional multiple data sets for storage 307 a-n. Client computing devices 310 and 311, as well as desktop device 312, connect to server 302 via Internet 301. Functionally a desktop computer is very similar to a smart phone, except that the relationship between performance and display and operating system, etc. is different, and a desktop computer has typically a much larger display. Also, in server 302, whether a single server or a cluster, each node is just a specialized version of generic computing device 200. Cloud computer arrangement 300 enables applications to cooperate between one or more of the client devices and the cloud, where some functionality is performed in the cloud and some is on the device. Further, it may not always be clear what operations are being done where, and operation locations vary from situation to situation, as well as varying according the capabilities of the computing device used.

In some cases, countries may have export industries, often but not exclusively related to mineral commodities that overshadow the rest of the economy and can created undesired appreciation of the domestic currency. That makes it difficult to export other goods and services, as they are often not related to those commodities, but cannot be competitively priced due to the currency issues. By isolating the commodity business with a separate, internationally tradeable crypto coin or token, in some cases also mineable coin, the effect of the commodity on the rest of the economy can be minimized, as only a part of the profits need to be re-patriated, where as the rest can be invested globally without affecting the local economy in a negative way.

In some specific cases, an exporter country may create an additional currency as a weighted basket targeting its two or three primary export market countries' currencies as the main weight, such stabilizing the prize of its commodity for its customers, and maybe adding the currency of a main supplier country or two for capital equipment for extraction or processing that export item as well.

In some cases, a system may have a multitude of nodes, each of which is capable of processing and managing a demarcated and sharded, or subdivided, blockchain. Each node would be in constant communication with at least four more nodes with the same or similar capabilities, one of which claims to be the lead node of the blockchain. Also, each node could add transactions and confirm the lead's transactions on the current demarcation subblock or shard. In case of loss of connectivity to the lead node, one of the remaining nodes could immediately take over as new lead node based on a CDMA/CD type protocol and be recognized by vote as the new lead by all remaining nodes. Further, after a certain subblock size is reached, a new subblock is started. Likewise, after a certain shard size is reached, a new shard is started. At a later time, older sub-blocks or shards could be consolidated according to rules into complete blocks and closed off after a vote.

In various aspects, functionality for implementing systems or methods of various aspects may be distributed among any number of client and/or server components. For example, various software modules may be implemented for performing various functions in connection with the system of any particular aspect, and such modules may be variously implemented to run on server and/or client components.

In some cases the system for transacting multiple payment token on multiple blockchains has at least one processor with memory, non-volatile storage for storing software including but not limited to operating system, applications, drivers etc., input/output devices, user interfaces, communication and network devices of all types etc.; the application software allowing to perform a finite number of steps including but not limited to accepting a non-permissioned type of crypto currency into a cold-storage facility with the intent to issue an Token representing said non-permissioned crypto currency on a permissioned blockchain, transfer said Token to a wallet on said permissioned blockchain representing the same value in real time, finding at least one second person or entity willing to transact on said Token, and once a price has been agreed upon, a transaction is closed and the crypto currency is later delivered from the cold storage for clearing the transaction. Further, in some cases, delivery takes place into another cold storage. In some other cases delivery is into the same cold storage. In yet other cases an additional verification code is requested before final delivery from the cold storage. Furthermore, in some cases, all the transactions are fully requiring KYC and AML clearances beforehand. In some cases, a cryptocurrency holder and/or cold storage facility owner can lend eToken to another party and receive interest payment.

The skilled person will be aware of a range of possible modifications of the various aspects described above. Accordingly, the present invention is defined by the claims and their equivalents. 

What is claimed is:
 1. A system for secure transactions in an environment with intermittent connectivity via a network to a blockchain, comprising: a merchant device comprising a first processor, a first memory, a first display, a first camera, and a first plurality of programming instructions stored in the first memory which, when operating on the first processor, causes the merchant device to: generate a first two-dimensional barcode representing a transaction, the first two-dimensional barcode comprising a merchant identity, a transaction amount, and connectivity details for a private peer-to-peer ad hoc network with the merchant device; display the first two-dimensional barcode on the first display; where a connection is established between a buyer device and the merchant device via a private peer-to-peer ad hoc network, receive a confirmation of the transaction from the buyer device via the private peer-to-peer ad hoc network, the confirmation comprising a buyer identity and an approval of the transaction; where a connection is not established between the buyer device and merchant device via the private peer-to-peer ad hoc network, receive an image via the first camera of a second two-dimensional barcode displayed on the buyer device, the second barcode comprising the confirmation; store a record of the transaction and confirmation, and when a network connection between the merchant device and a transaction blockchain becomes available, send the record of the transaction to the transaction blockchain for recording; and wherein the buyer device comprises a second processor, a second memory, a second display, a second camera, and a second plurality of programming instructions stored in the second memory which, when operating on the second processor, causes the buyer device to: receive an image of the first two-dimensional barcode displayed on the merchant device via the second camera; where a connection is established between the buyer device and the merchant device via the private peer-to-peer ad hoc network, receive a user interaction at the buyer device initiating the confirmation and transmit the confirmation to the merchant device; where a connection is not established between the buyer device and the merchant device via the wireless network connection, generate a second two-dimensional barcode representing the confirmation, the second two-dimensional barcode comprising the buyer identity and the approval of the transaction; and display the second two-dimensional barcode on the second display.
 2. The system of claim 1, wherein either or both of the buyer and merchant devices are antitamper-hardened devices.
 3. A method for secure transactions in an environment with intermittent connectivity via a network to a blockchain, comprising the steps of: generating, on a merchant device comprising a first processor, a first memory, a first display, and a first camera, a first two-dimensional barcode representing a transaction, the first two-dimensional barcode comprising a merchant identity, a transaction amount, and connectivity details for a private peer-to-peer ad hoc network with the merchant device; displaying the first two-dimensional barcode on the first display; receiving a network connection attempt with the merchant device from a buyer device via the private peer-to-peer ad hoc network; where a connection is established between the buyer device and merchant device via the private peer-to-peer ad hoc network, receive a confirmation of the transaction from the buyer device via the private peer-to-peer ad hoc network, the confirmation comprising a buyer identity and an approval of the transaction; where a connection is not established between the buyer device and merchant device via the private peer-to-peer ad hoc network, receive an image via the first camera of a second two-dimensional barcode displayed on the buyer device, the second barcode comprising the confirmation; store a record of the transaction and confirmation, and when a network connection between the merchant device and a transaction blockchain becomes available, send the record of the transaction to a blockchain for recording; receiving an image of the first two-dimensional barcode displayed on the merchant device via a second camera of a buyer device comprising a second processor, a second memory, a second display, and the second camera; making the network connection attempt to the merchant device using the connectivity details for the private peer-to-peer ad hoc network; where the connection is established between the buyer device and merchant device via the private peer-to-peer ad hoc network, receiving a user interaction with the buyer device initiating the confirmation, and transmit the confirmation to the merchant device; where a connection is not established between the buyer device and merchant device via the wireless network connection, generating a second two-dimensional barcode representing the confirmation, the second two-dimensional barcode comprising the buyer identity and the approval of the transaction; and displaying the second two-dimensional barcode on the second display.
 4. The method of claim 3, wherein either or both of the buyer and merchant devices are antitamper-hardened devices.
